Abstract
A food dispensing machine includes a product chamber and an ingredients source including a gas source connected to the product chamber. A flow control device is configured to control ingredients flow from the ingredients source to the product chamber. A pressure measurement device is configured to output a gas pressure signal, and a controller is configured to receive the gas pressure signal and determine a gas flow control signal based on the gas pressure signal. The controller outputs the gas flow control signal to the flow control device.
